Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687492, here are decompositions:
- 13 + 8687479 = 8687492
- 31 + 8687461 = 8687492
- 109 + 8687383 = 8687492
- 193 + 8687299 = 8687492
- 283 + 8687209 = 8687492
- 823 + 8686669 = 8687492
- 991 + 8686501 = 8687492
- 1021 + 8686471 = 8687492
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,687,492 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
